Definitions
- This invention relates to improvements in the production of dried fructose products from fructose solutions, and more specifically to a procedure for spray drying fructose solutions in the presence of recycled product solids to obtain dry, finely divided, free-flowing particulate fructose solids.
- the present invention is applied to the process for spray drying fructose solutions which have been obtained by conventional processes such as the recovery of fructose from invert sugars, or compositions containing invert sugars such as molasses.
- Fructose which has been obtained by methods such as the enzyme conversion of sucrose or glucose to fructose may also be used. It is generally preferred that the fructose solutions contain little or no impurities; however, solutions containing minor amounts of other sugars, such as sucrose or glucose, may be utilized.
- the present process involves dispersion, that is, atomization, of fructose solution into the hot air flowing in a spray dryer while separately feeding substantial proportions of solid fructose particles.
- the fructose solution may contain from about 30 to about 100 weight percent solids. Where appropriate or desirable, the solution is preheated to aid in pumping and atomization.
- the solid fructose, preferably recycled product, is separately and concurrently fed to the dryer in amounts sufficient to provide a weight ratio of from 1 to 10, preferably about 3 to about 7 parts of solids, for each part by weight of solids in the solution to be dried.
- the weight ratio of solids in the solution to the separately introduced recycled product solids ranges from about 1 to about 0.1, preferably from about 0.33 to about 0.14.
- the inlet temperature of the hot drying gas preferably is in the range of from about 100 to about 300°C, and the outlet gas temperature is about 78° to about 90° C.
- the average air residence time is preferably from about 5 to about 20 seconds.
- the presently most preferred embodiment of the process of the present invention includes as a further feature the use of recycled fructose product solids having an average particle size of not greater than about 500 microns and preferably not greater than about 200 microns. It is generally undesirable to reduce the average particle size of the product to be recycled below about 50 microns, and preferably the recycled solids will have an average particle size within the range of from about 50 to about 200 microns. Average particle size as used herein means that size where 50 weight percent of the particles are larger and 50 weight percent are smaller.
- the most surprising aspect of the present invention is the observation that the unusually high drying temperatures do not result in any noticeable burning and/or darkening of the dry product. This is a truly unexpected result when considered that fructose melts at about 95°C and is known to seriously degrade when heated to temperatures which approach about 110°C. Thus, this invention eliminates the normally practiced addition of materials that inhibit or retard degredation of fructose which occurs at high temperatures.
- the spray drying operation presently described herein is conducted in conventional equipment such as that disclosed in U.S. Pat. Nos. 3,600,222; 3,704,169 and 3,706,599.
- the spray dryer is operated to dispense the fine size recycle product at the outer periphery of the drying zone as an enveloping solids-bearing atmosphere about the droplets of fructose solution being dried.
- the dried fructose which is collected from the spray drying zone is conducted to a conditioning zone wherein the still warm dried fructose is conditioned, that is, held quiescently or mechanically agitated.
- the conditioning of the fructose product permits the formation of particles which are particularly discrete and free flowing.
- the conditioning of the product may be conveniently conducted using a stationary container or a conventional rotating drum conditioner which is ordinarily used in the sugar industry.
- the particulate fructose obtained by the process contemplated herein is stable to long term storage and is particularly suitable as a commercial sucrose substitute.
- a fructose liquor containing 70 weight percent fructose was dried in a spray dryer having a 2.5 ft. diameter, a 6 ft. drying cylinder and a 3 ft. product collection cone.
- the dryer surface area and volume were 63.8 ft 2 and 35 ft 3 respectively.
- the fructose liquor was dispersed through a two fluid nozzle at the dryer bottom with 60 psig air while air was fed into the dryer at the top, resulting in mixed flow drying.
- Recycle solids were air conveyed to the drying chamber through a half-inch ID tube located about half way up the drying cylinder tangentially to the dryer walls.
- fructose liquor at ambient temperature was fed to the two-fluid atomizer at a rate of 0.26 pounds per minute (equivalent to 0.18 pounds solids/minute).
- the ratio of recycle solids to liquor solids was 5.0.
- the recycle solids for the run was crystalline sucrose with a particle size of about 200 microns.
- Air was fed to the dryer at a rate of approximately 300 cubic feet per minute, giving an average dryer resistance time of about 7 seconds.
- the air inlet temperature ranged from 143° to 165°C.
- the outlet air temperature ranged from 82° to 88°C.
- Example II Another run was conducted in the same equipment and under conditions generally similar to those of Example I. In this run all recycled solids were crystalline fructose with a particle size of about 400 microns. The inlet air temperature was 160°C and air outlet temperature was 88°C.
- the recovered product was a white particulate solid which upon conditioning for about one hour at ambient temperature was free flowing.
- the total moisture content of the product was less than 1 percent. There was no noticeable darkening or off-white character or "burned" taste to the product.
- Example II Another run was conducted in the same equipment and under conditions generally similar to those of Example I.
- solid product from Example II was used as recycle solids.
- the inlet air temperature was 158°C and air outlet temperature ranged from 83° to 85°C.
- This exemplary run was essentially a repeat of Example II.
- the inlet air temperature ranged from 138° to 149°C and air outlet was 85°C.
